Immediately after the shed, change direction (2,6)
I believe the answer is:
by return
'immediately' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'after the shed change direction' is the wordplay.
'after' says to put letters next to each other.
'the shed' becomes 'byre' (I've seen this before).
'change direction' becomes 'turn' (I've seen this before).
'byre' next to 'turn' is 'BY RETURN'.
Can you help me to learn more?
(Another definition for by return that I've seen is " next post".)
